BUILT FROM REAL SELLING EXPERIENCE
Made by an Amazon seller—not by people guessing how sourcing works.
SellerScorer was built by a 7-figure Amazon seller in California after five years of evaluating products, watching margins disappear, and needing a faster way to separate good inventory from expensive mistakes.
THE EXACT OUTPUT
One panel answers: should I buy this?
Enter your cost. SellerScorer shows the net profit, ROI, margin, maximum buy cost, monthly demand, effective competitors and suggested quantity before you spend money.
True profit, not estimates
Calculate referral fees, FBA fulfillment, inbound placement, prep, shipping, tax, reserves, and every cost that changes the deal.

Competition that counts
Separate FBA, Prime FBM, and regular FBM. Weight sellers by price proximity instead of treating every offer equally.

TRY THE DECISION ENGINE
Not every profitable-looking product is a buy.
Switch between three sourcing scenarios. SellerScorer weighs the whole deal—not just sale price minus cost.
